Recall 14V469 affects 5 2009 Schwarze M6000SE Cng street sweepers for frozen intake condensation. ECM calibration is free at any franchised Schwarze dealer.
Schwarze is recalling 5 2009 M6000SE Cng street sweepers under recall 14V469 because condensation in the intake manifold can freeze in cold weather and disrupt the intake manifold pressure sensor. That sensor problem can raise exhaust temperatures or send flames from the exhaust pipe, increasing fire and burn-injury risk; the dealer repair will be free once available.

What's wrong?
The intake manifold on the 2009 Schwarze M6000SE Cng street sweeper routes the air and fuel mixture into the Cummins Westport Model ISL G engine. Its pressure sensor reads pressure inside that manifold so the engine controls know how much air is moving through the intake. That reading helps the engine manage combustion on the CNG system.
In cold weather, condensation inside the intake manifold can freeze. Ice at or near the pressure sensor interferes with the sensor's ability to read manifold pressure correctly. When that reading is blocked or distorted, the engine is working from bad intake-pressure information instead of the actual air flow through the manifold.
There is no warning sign before failure. A driver should not count on a noise, smell, warning light, or change in engine feel before the sensor is affected.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone near the pipe. Schedule the ECM calibration repair promptly, and keep people clear of the exhaust area while the vehicle is running. Repair will be free at any franchised Schwarze dealer once available.
What should I do?
- Check your VIN to confirm your 2009 Schwarze M6000SE Cng is included in this recall.
- Use the owner notice Schwarze mailed in July 2014, or call Schwarze customer service if you never received it.
- Contact a franchised Schwarze dealer to ask about the free ECM calibration that corrects the intake-manifold pressure sensor problem.
- Reference recall number 14V469 when you call the dealer or Schwarze customer service.
- Avoid idling near people or structures until the calibration is complete, because the exhaust can overheat or produce flames.
What happens at the repair
At the dealer, a Schwarze technician uploads a new ECM calibration for the Cummins Westport ISL G engine. The calibration is meant to address intake manifold condensation that can freeze in cold weather and interfere with the intake manifold pressure sensor. Schwarze notified affected owners, and the recall began in July 2014. The dealer repair is free under the recall. Owners can contact Schwarze customer service or Cummins with repair questions tied to campaign 14V469.
